[0019] The following examples are used to describe the implementation of the present invention in detail, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.
[0020] The present invention provides an improved neural network pedestrian re-identification method based on triple loss, which specifically includes the following steps:
[0021] Step S1: Construct a sample database, and expand the number of each sample picture in the sample database, from the original one sample picture to eight sample pictures to form a small data set; specifically, one sample picture is separately Translation in four directions: upper left, upper right, lower left, and lower right, the scale of translation is: y=height×(±0.5), x=width×(±0.5); along the center of the sample picture, press counterclockwise and clockwise respectively Rotate 5°; mirror the sample picture, through the abov...
